Versioned name: BiasAddBackprop-1

Category: Arithmetic

Short description: Computes the gradients on the “bias” tensor for add bias operator.

Detailed description:

This op accumulates all the values from output_delta into the channel dimension, the axis depends on the layout of input tensor.


  • 1: output_delta - gradients tensor w.r.t. the output. Required.


  • data_format

    • Description: data_format denotes the data format of the input.

    • Range of values: NXC or NCX (X means HW for 2D, DHW for 3D)

    • Type: string

    • Default value: NXC

    • Required: no


  • 1: bias_delta - gradient tensor w.r.t. bias.
